Description

[Detailed description of the invention] [Industrial field of application] The present invention uses a plurality of pairs of vertical strings that connect an oblong upper frame and a weight positioned below the upper frame to face each other. The present invention relates to an improvement in a blind in which a large number of horizontal blades supported at predetermined intervals are provided, and the horizontal blades are rotatable around a horizontal axis and can be raised and lowered.

[Conventional technology]

Conventional blinds of this type have the following problems. In other words, even if the solar altitude changes, the sun's rays can be blocked by rotating the horizontal blades around the horizontal axis and adjusting the angle, but depending on the azimuth of the sun, the rays may be blocked from the ends of the horizontal blades. It may be inserted. In particular, when multiple blinds are installed side by side inside a row of windows, there is no problem if the joint between the blinds matches the position of the mullion, but if this is not the case (ready-made (When installing blinds, the width of the window does not necessarily match the width of the window, and the joints between the blinds may shift from the position of the mullions.) Direct sunlight can shine through the joints,
The original function of the blinds is not fully demonstrated.

[The problem that the idea aims to solve]

In view of the above-mentioned conventional drawbacks, the present invention allows direct sunlight to shine from the end of the horizontal blade even if the azimuth of sunlight changes or even if the joint between the blinds does not match the position of the mullion of the multi-window window. The objective is to provide an easy-to-operate blind that can block sunlight from entering.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a vertical blade winding box having vertical blades that are biased for winding, at a position above the horizontal blade end of the upper frame of the blind described at the beginning. It is characterized in that it is rotatably attached around the core, and the lower end of the vertical blade is attached to the weight so as to be rotatable around the vertical axis.

[Effect]

According to the above configuration, the vertical blade moves up and down in conjunction with the raising and lowering of the horizontal blade (raising and lowering the weight),
The vertical blades will block direct sunlight from the ends of the horizontal blades.

Since the vertical blades are rotated around the vertical axis by rotating the vertical blade winding box around the vertical axis, it is possible to cope with changes in the azimuth of sunlight.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

In FIG. 1, 1 is a blind. The blind 1 includes a horizontally elongated upper frame 2 in the shape of a hollow box attached to the upper part of the window frame, a horizontal straight rod-shaped weight 3 parallel to the upper frame 2, and the weight 3 is suspended and supported by the upper frame 2. Multiple pairs of belt-shaped vertical cords a...
and a large number of horizontal blades 4 supported at predetermined intervals by these vertical cords a.

The blind 1 is provided with two types of operating strings b and c, and by operating one string b, all the horizontal blades 4 can be rotated around the horizontal axis at the same time to adjust the angle, and the other By operating the string c, the horizontal blades 4 can be raised and lowered together with the weight 3, but since these specific mechanisms are well known, illustrations and explanations thereof will be omitted.

5 is a vertical blade for preventing sunlight from penetrating through the edges of the blind or the joint between the blinds. The vertical blade 5 is biased in the winding direction by a coil spring or the like provided in a vertical blade winding box 6. The box 6 is pivotally supported at a position above the horizontal blade ends of the upper frame 2 via pins 7, 7, and is rotatable around the vertical axis. The lower end portion of the vertical blade 5 is pivoted to the weight 3 by a vertical pin 8, so that it is rotatable around a vertical axis substantially coaxial with the vertical axis.

Therefore, by rotating the box 6 and the lower end side of the vertical blade, the entire vertical blade 5 can be rotated. However, since the vertical blades 5 have some rigidity, simply by rotating the box 6, the vertical blades 5 can be rotated together to the lower end side.

It is desirable that the box 6 can be rotated from below, and in that case, as shown in FIGS. The gear 10 and the gear 11 may be engaged with each other via the gear 10 and the gear 11, which can be rotated by the lever 10a. The gear 11 is provided to make the direction of rotation of the lever 10a coincide with the direction of rotation of the box 6. still,
It is desirable that the center of rotation (vertical axis) of the box 6 be as close to the center position of the vertical blade 5 as possible. This is to minimize the movement of the vertical blades 5 from side to side when the box 6 is rotated. Also, the rotation angle of the box 6 can be set as appropriate;
Normally, it is preferable to be able to rotate about 45 degrees left and right. Figures 4A and 4B show the state in which sunlight is blocked when the vertical blades 5 are rotated 45 degrees left and right.

[Effect of idea]

Since the present invention has the above-described configuration, it can achieve the following effects.

Vertical blades are provided at the ends of the horizontal blades of the blinds, so when multiple blinds are installed side by side, even if the joints between the blinds do not match the mullions, sunlight from the joints can be effectively absorbed. can be shut off.

Since the vertical blades are rotatable around the vertical axis, even if the azimuth of sunlight changes depending on the time of day, this can be dealt with by rotating the vertical blades.

Since the vertical blades can be moved up and down in conjunction with the raising and lowering of the horizontal blades, there is no need to separately move the vertical blades up and down, and the operation feels similar to that of conventional blinds. Therefore, while the operation feeling is the same as that of the conventional one, it has the effects described in .
It has great practical value.
